HouseTrip is a service rather likes Airbnb, that puts holiday home owners in contact with people looking to rent a house for vacation. The new iOS app includes a messaging tool so you can speak to the home owner, alerts you to attractions in the area, and helps you to plan your itinerary.

The app uses Foursquare to make suggestions about places to visit whilst on vacation—great if you need to find somewhere to eat, or want to track down the nearest coffee shop. The HouseTrip app also includes an itinerary planning tool so you can schedule when you want to do while you're away.

Hopefully your vacation will be problem-free, but there is a chance you might want to ask the home-owner a question—perhaps asking for recommendations for shops. There is a built-in messaging system that you can use to talk with your host.

The app is currently available for iOS, but there is an Android version on the cards as well.
